1. A system for measuring electrical activity generated within a brain, the apparatus comprising:
- a headpiece including a stretchable substrate,an integrated circuit formed on the stretchable substrate,an insulating layer formed on the integrated circuit,a plurality of electrodes arranged on a surface of the insulating layer, the plurality of electrodes configured with fixed relative positions to provide a spatial resolution of less than 1 centimeter over the brain,a plurality of vias extending through the insulating layer, each of the plurality of vias connecting the integrated circuit to an electrode of the plurality of electrodes, wherein the headpiece is placed in contact with a head that contains the brain to conform the substrate and integrated circuit to the shape of the head to bring the plurality of electrodes into contact with the head, wherein the integrated circuit includes;
a plurality of FinFETs that perform signal acquisition, signal analysis, noise reduction and pattern recognition, anda processor that receives signal features and sensor locations from the plurality of FinFETs and provides a diagnostic interpretation based on the electrical activity in the brain; and
a remote processor for receiving the diagnostic interpretation from the processor and showing the diagnostic interpretation at a display.

Abstract
A method, apparatus and system for measuring electrical activity generated within a brain is disclosed. A headpiece having a first transistor is placed in contact with a head that contains the brain to bring the first transistor into electrical contact with the head. An electronic signal is generated at the first transistor in response to the electrical activity generated within the brain. The electronic signal is processed at the headpiece in order to measure the electrical activity.
